Themain can casing I, handle 2, casing screwgo bottom 3, puncturing andclosure lever'l, can puncturing and spout forming lug'5, vent puncturinglug 6, spring 1, and lever support 8, constitute the principal parts andportions of my milk can opening forming andpouring attachment. a V

i The main can casing I is cylindrical in formv and closed at its top orupper end and is adapted to fit the can when placed therein but permitsthe easy slipping of the can into the same. It

is screw-threaded around its lower end on which is adapted to screw thecasing screw bottom 3 so that the can. is entirely enclosed therein.This casing is provided at the front upper side with an enlarged oii'setportion Id, asshown best in Figs. 1 and 3fo'f the drawing, which isadapted to permit the turning of the formed spout in the can to aposition where itwill'enter enlarged longitudlnal portions lb dependinguponthe direction it is'turned to facilitate the removing of the cas- 40I ing.fromthe can. It willbenoted that the por- Ninth, to providean'attachment of this class tions lb arecut away at the bottom leavingslots in the casing I at the bottom over which the screw bottom extendswhen it isin pQSitiOILBS .shown in Fig. 1 of the drawing. The casing iis "also provided withreinforcing ridges or corruga- ;tionsf lc at itsside. The casing l is also provided with openings id and le to permitthe can puncturing lugs to pass through for puncturing and forming thecan. The casing is provided at its normally back side with a handle 2'which is adapted to facilitatethe handling of the casing with the canduring the pouring operation and otherwise.

Secured to the back side of the casing immedi- 88 ately above the handle2 is the lever support 8 which is a channel member and bifurcated at itsupper end. Between the bifurcated portions the lever 4 is pivotallymounted on a pin Ba. Secured through the members of the channel of thelever support 8 is another pin 8b on which is mounted a coil spring Iwhich is provided with extended ends, one extending end engaging theextended end 4a of the lever 4 and the other end resting against thesurface of the support 8, thus supporting a coil spring means fortending to cause the lever 4 to move downwardly at the puncturing end,the portion 4a forming a handle which is adapted to be grasped by thethumb of the user for raising and lowering the lever 4 relative to thecasing l. Secured to the lever 4 adjacent the support 8 so as to engagethe side of the can through the opening le is a vent puncturing lug 6which is preferably a round very sharp pointed relatively small lug forproviding a vent in the side of the can towards the handle. Atthe'opposite end of the lever 4 from the handle 4a is a downwardlyextending lug 5 which is provided with a very sharp edge 5a which isadapted to puncture the can close to the front edge thereof. Itis'provided with a forwardly tapering portion 5b ,which is adapted topress the edge of the can outwardly forming a pouring spout, as shownbest in Fig. 6 of the drawing. This upper edge is again forced outwardlypast the side of the main portion of the casing i so that the contentsof the can will not run down of spill down between the casing and canand will a readily pour from the can when the lever 4 is lifted out ofthe way by pressure of the thumb on the portion 4a of the lever 4.

It will be noted that the front portion of the lever 4 at its upper sideis preferably rounded at 40 at the sides so that the spout formed in thecan is rounded and extended.

It will be noted that the lugs 8 penetrate the can first, then the lug 5begins penetration of the can after the penetration of the lug 6 so thatthe can is initially punctured at different times so that less pressureis required for puncturing and forming the can for pouring purposes.

The operation of my attachment is asfollows: The casing screw bottom 3is removed from the casing l by screwing it off and a can is positionedin the casing I. Then the bottom 3 is screwed onagainst the bottonrbfthe can holding the can rigidly in position in the casing. Then thecasing is placed on its bottom and pressure is brought to bear on thelever 4 which causes the lug 5 first to enter the side of the can, thenthe lug 5, thus providing a vent at onefside and a pouring spout in thecan at the opposite or front side. pouring purposes. By taking hold ofthe handle 2 the user presses the thumb on the end 4a of the lever 4depressing the same and the hole is tilted forwardly the same as apitcher for pouring from the can, after which the portion 4a. isreleased and the spring 1 causes the lever 4 to move downwardly wherebythe lugs 5 and 6 enter the openings in the can and they are quickly Thenthe can is ready for use for sealed by the milk around the small openingand may be thus used until the can is empty. In removing the can thebottom I is removed, then the can turned in the casing i until either ofthe enlarged portions lb is reached and the casing then taken from thecan.

Though I have shown and described a particular construction, combinationand arrangement of parts and portions, I do not wish to be limited tothis particular construction, combination and arrangement, but desire toinclude in the scope of my invention the construction, combination andarrangement substantially as set forth in the appended claims.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. In a milk can opening forming and pouring attachment, a casingsubstantially closed at its upper end and open at its lower end forreceiving a can and provided with an enlarged offset por tion at itsfront upper side, a handle therefor, a lever pivotally mounted on saidcasing adjacent said .handle and provided with a handle extendingportion, and a spout forming lug forming the free end of said lever,said spout forming lug consisting of a sharp pointed-member providedwith an upwardly diverging forwardly extending wall adapted to engagethe side upper edge of the can and distort itoutwardly against saidenlarged offset portion. 1

2. In a milk can'opening forming and pouring the can and distort itoutwardly against saidenlarged offset portion, said forming lug providedwith rounded portions at its upper front side. a

3. In a milk can opening forming and pouring attachment, a casingsubstantially closed at its upper end and open at its lower end forreceiving a can and provided with an enlarged offset portion at itsfront upper side, a handle therefor, a lever pivotally mounted on saidcasing adjacent said handle and provided with a handle extendingportion, a spout forming lug forming the free end of said lever, saidspout forming lug consisting of a sharp pointed member provided with anupwardly diverging forwardly extending wall adapted to engage the sideupper edge of the can' and distort it outwardly against said enlargedoifset portion, said forming lug provided with rounded portions at itsupper front side and a vent puncturing lug secured to said lever nearits pivotal mounting.
